Finally got a working wiper motor, came with the 2 speed switch that also parks the wipers when the switch is turned to off. Problem is the switch is not long enough to fit through the dash. Is there another switch that can be used in place of the original? Could I use a universal 2 position switch?As always – thanks for any and all information!DonnaApril 24, 2012 at 7:12 pm #250229Dan RosaParticipant
Donna , I have one for a boat that i got from Bass Pro Shop with park for i ‘m thinking under $10.00 it adjusted to a full 1.25 inches Good luck Dan RApril 24, 2012 at 7:56 pm #250230
Thanks Dan – There is a Bass Pro Shop about 30 minutes away. I’ll also do some checking at 2 other boat places that are closer, too.April 24, 2012 at 9:11 pm #250231edward ericsonParticipant
If your problem is a 3/4-inch slab of wood for a dash, you could also use a blade drill to relieve the inside of it. Overdrill through the fiberglass first–an inch and a half diameter hole will more than do it; smaller is better. Then put a 1 1/8 inch wood bit in the wiper switch hole from the back. Crank it in a quarter inch and test fit the switch, etc.
I say this because, from my reading of several forums on Samba and other places, it appears that VW wiper switches are pretty unusual, if not unique. I got my one-speed boat wiper motor to work with my stock switch, but people trying to get their stock VW 2-speed wipers to park right with any switch other than the correct year VW switch were seen pulling their hair out.April 26, 2012 at 12:26 am #250232PhilParticipant
I got my wipers to park correctly by inserting a diode into the park circuit of the motor.PhilApril 26, 2012 at 7:10 am #250233newkitmanParticipant
Been following this thread in the background. If I understand what I’m reading, most of you are running the original VW wiper switch rather than the 4-post switch that comes with the TD kits. Is this correct? I ask because I’m just now wiring my dash and if there is a problem with the kit wiper switch, now is the time to correct mine.

I used the switch provided in my Duchess kit, with a 1970 VW two speed wiper motor.Works fine and the wipers “park” automatically whne you turn them off.

Park, is in the wiper motor transmission there is like cam that kills power at the park position that is why there 2 power wires. DanApril 26, 2012 at 1:06 pm #250236newkitmanParticipant
Thanks for the info. I also found a wiring schematic for the stock VW Wiper motor. I was confused at first because the power wire and the park wire were connected on the same terminal of the switch. Seemd to me they would be fighting each other. BUT…with the switch turned on, the power by-passes the park circuit (offer less resistance I guess) and runs the motor either in high or low power. Again…thanks for your input as well. Always good to learn.

Allen, Sounds like the schematic is wrong if the “run” and “park” wires of the motor are shown as connected to the same terminal on the switch. (It wouldn’t be a first.) Typical wiring has the “park” power supplied by anything that is hot when the key is on.April 26, 2012 at 2:01 pm #250238James CochranParticipant
Donna,My wiper switch stem was not long enough either, so I carved a pocket in the backside of the wood dash for the switch body to rest, and it works perfectly.April 28, 2012 at 10:21 pm #250239
Finally got the wipers working. Called most every boat supply store, auto parts, etc. looking for a switch for 2-speed wiper with park, no luck with any of them. Went over to the Samba site and found several forum post about wiper switches. Hooked up a simple toggle (on / off / on) by following a drawing that was posted. Wipers are working great!
